Y., A CORPORATION OF NEW YORK I ELECTRIC VAPORIZER Application led November 27, 1928, Serial No. 322,254.l Renewed September 4, 1930.

This invention relates vto electric Vaporizers.

Among the objects of the present invention is to provide an electrically heated vaporizer, which `is adapted for luse only in conjunction with its associated mounting and in ywhich energization of the heating elements is prevented except when such elements are properly positioned within the receptacle.

A further object of the present inventionv is to provide in a vaporizer, a receptacle, the

bottom of which is other than flat, whereby the use of the device without its receiving 4 4 of Fig. 3;

support is prevented.-

Another object of the present invention is to provide in a device of the character set forth, means for preventing the energization of the heating element while said element is other than received Within the receptacle, and also to provide for the preventing of the removal of the heating element from the receptacle While being energized from an outside source of power.

A further object of the present invention is to provide in a device ofthe character set forth, a guard or cover adapted for` association with a seal for the receptacle, which guard or cover is adapted to retain the seal in airtight relation with the receptacle *and to assist in' controlling the energization `of the heating element forming part of the present combination.

A still further object of the invention is to lprovide a device of the character set forth in which a portion of the stand is adapted to move vertically with the movement of the cover, whereby the receptacle israised as the cover is lifted, such raising being adapted to disengage the receptacle from the stand, and thus to prevent operation of the device while the cover is open.

Other objects of the present invention include the combination and interrelation of parts, whereby the invention provides anovel and improved structure well adapted for the requirements of economical ncanufacture, and through the use of which accidents are prevented by the prevention of energization of the heating elements when said elements are not received within a receptacle or when said receptacle is not received within its support.

Numerous other objects and features of the present invention will be apparent from a consideration of the., following specification taken in' connection with the accompanying drawings, in which Figure 1 is a. perspective view of one form of my present invention; j

Referring more particularly to that form of the invention illustrated in Figs. 1 to 6, inelusive, there is provided a receptacle 10the upper open end of which is provided with a thickened peripheral rim 11, the lower'closed end ofwhich receptacle in the form shown is substantially convex, as vat 12, or otherwise of configuration adapted to prevent the vertical position as illustrated in Figs. 1 and 2, except when the device is received within its associatedsupport.

For receiving this particular receptacle 10, a, skeleton frame 13 may provided including a flaring base 14, side members 15, handle 16, `and annularly extending upper rim 17 with which there is associated in hinged reihtion thereto, a skeleton guard or cover formed 'of a peripherally extending rim 18, opposite to the hinged portion of which there is provided a.V resilient catch 19 adapted for engagement through an aperture in one of the side members 15, substantially as disclosed.

For heating a liquid received within the receptacle 10, there is provided a pair of suitable electrical heating elements or electrodes projecting downward from a sealing cover 21'into the receptacle 10. Projecting from.

c. 4the upper surface of the cover 21, electrical va orize quent Icontacting fingers 22 are provided adapted .hinged guard or cover y18 of the support 13 must be -moved to release the cover 21 from the receptacle 10, the hinged movement required, however, being prevented by the association of the fingers `22 with the plug 23.

Thus'theA removal of the plug -23 and consecessation of the energization of the elements 20, must `become a prerequisite ofthe removal of the sealin cover 21. Referring to 4 To provide for the the drawings it will noted that the fit of the cover 21 with respect to the receptacle 10, is loose and such that the engagement of the hinged cover 18 with the receptacle 13, as by means of the catch 19, is required to prevent leakage of the vaporized liquid from the device. Thus the receptacle 10 as shown must be received within the support 13 to -peroperly operate the device. It will further seen that the convex configuration of the lower end of the receptacle 10 is such that it cannot be properly supported other than in the support 13.

It will be'understood that while I have shown my device as being supported in a support or frame, I do not care to be limited to such structure, as it is quite apparent that the ybottom of the receptacle may be made flat so that it may be set upon any desired object without a supporting frame.

It will be further apparent that while l have designated the securing part for the lid as a cover,.that its function is really a securing device and guard for the lid in that it not only secures the lid tion upon the receptacle, but it also provides a guarding means whereby the breaking of the connection must cover or guard is moved suiciently to allow the lid to be opened.

proper alinement ofthe in a gas-tight posi` spout 25, whereby the hinged cover member 18 may be moved without interference therewith, the sealing cover 21 with which the spout is rigidly associated, is provided with a projectingvportion 26, which must be received in a complementary depression 27 of the rim 11 of the receptacle 10, before the sealing cover 21 may be received to seal the receptacle 10 and thus before the hinged.

cover 18 may be closed to retain the cover member 21 in proper relation with the receptacle 10.` The registration herein referred to must of necessity be inv conjunction with a specific positioning of the receptacle 10, to

provide for the proper relation of the spout 25. The specific positioning of the receptacle 10 is provided for by a projecting member y28 receivable within a cut-out *port-ion 29 of the base 14, substantially as illustrated.

From the foregoing it will readily be seen that this formfof the invention provides a device incapable of proper operation at any time other than when the receptacley is properly received and fitted within its support`13 and the sealing cover 21 properly received by thereceptacle and the cover 18 closed. It will also vbe readily seen that en'ergization of the sealing elements 20 will not be permitted at such times other than when the elements 20 are properly received within the receptacle 10. It' will thus be apparent that the invention provides a device of the character s'et forth in which injury due to the energizedeletake place when this( ments orelectrodes 20 coming in contact with the operator or with fixtures other than the associated fixtures of the apparatus. The invention thus provides a simple, safe and convenient structure.

Referring more particularly to Figs. 7 and 8 of the drawings in which there is illustrated a modification of the invention, the sealing cover 21 of the receptacle 10 is provided with projecting conducting fingers l30 which are adapted to be received within the lower end of associated conducting fingers 31- carried by the hinged cover member 18. The construction will be readily 'seen to bev such that upon hinged movement of the cover member 18 with respectrto the top 17 of the support 13, the electrical connection between the fingers 30 and- 31 will be broken, thus providing for the automatic de-energization of the sealing elements 20 when the cover 18 is raised. y'It will also be readily understood that the form of the invention herein illustrated is butone specific embodiment ,of the structural features which ,may be utilized to carry out this form of the invention and that the invention is not limited to the specific structure herein shown.

Referring more particularly to Figs. 9 and y 10, to insure the proper connection of the` hingedcover 18 with the peripheral rim 17 and thus to retain the sealing cover 21 with respect to the receptacle 10, the spout 25 is formed integral with the cover member 18, whereby when the cover 18 is firmly associated with the rim 17, by provision of the catch member 19, the spout 25 is/alined with the aperture 24 in the sealing cover 21. In this form of the invention/it will be seen that' movement of the hinged cover 18 with respect to the support 18 will release the association of the spout 25 with the aperture 24, thus permitting leakage of the vapors formed within the receptacle 10 and thus ensuring the proper relation of parts during all times that the device is in use.

Referring more particularly to Figs. 11, 12 and 13, this form of the invention provides for a vertically moving support 26, for receiving the receptacle 10, the support 26 being associated through a pivoted link 27 to a depending a-rm 28 carried by and movable with the hinged cover 18. The association of the link 27 and the arm 28 is adapted for limited lost motion by the provision of an elongated aperture 29 in the link 27, through which a connecting member 30 mounted upon the extremity of the arm 28 is adapted for partial free movement. The electrode-carrying cover and electrical connection therefor have in this instance been disclosed similar to that shown in Figs. 1, 2 and 3. It will be understood, however, that this form of the invention is adapted for cooperation with either the cover structure as disclosed or with the modification arrangements as shown in Figs. 7 to 10, inclusive. It will be readily seen that in this form of the invention, raising of the cover 18 automatically lifts the receptacle 10 from its support and retains it in a lifted unstaple position, thus preventing energization of the electrodes or other use of the device-while the cover is raised. It will be understood that the raising of the cover is accompanied by the prerequisite of removing the electrical supply plug 23,. as formerly discussed.

It will be understood that the present invention has been illustrated in specific structural features, but that numerous changes and modifications in the structural features of the device and the full use of equivalents may be properly resorted to without departing from the spirit or scope of the invention asA outlined in the appended claims.
